3-67 Section 3 - Operation

Drawbar Assembly

Drawbar Operation

The drawbar height is fixed and must not be altered.. It is designed to produce maximum traction for the wheelbase, tire size, weight distribution and ballast of the tractor.. The drawbar length is non adjustable..

The drawbar is free-swinging and should be positioned for the best performance and the least side draft.. There are five drawbar positions available.. To swing the drawbar, pull the hairpin clips (1) from the wear blocks (2).. Remove the wear blocks, swing the drawbar to the desired position and reinstall the wear blocks..

Choose a position that is right for the job and insert the pin and wear block in that position to keep the drawbar from moving..

It is recommended that the drawbar be pinned in position at all times.. On occasion, it may be necessary to allow the drawbar to swing freely for implements that place side loads on the rear of the tractor.. The drawbar can be used in a swinging application but may require replacement of the drawbar wear block after extended use..

Clevis-type implement hitches should be connected only to the lower plate of the drawbar.. Other hitches should be connected between the plates as shown on the decal on top of the drawbar wear block..

Automatic Hitch Pin

The drawbar is equipped with a hitch pin that will automatically drop in place when hitching up to implements..

To operate, place the hitch pin (3) in the raised position.. Retaining ring (4) fits in the upper notch (5) of the clevis to hold the hitch pin in the raise position.. Release strap (6) must be positioned in front of the retaining ring as shown.. The drawbar is now prepared to hitch to the implement..

When backing the tractor to attach the implement, the implement hitch will contact the release strap

(6)when aligning the drawbar.. As the release strap is pushed forward it dislodges the retaining ring (4).. Hitch pin (2) will drop as the retaining ring (4) slides down the incline (7) on the front of the clevis.. The implement is now attached to the tractor without requiring the operator to leave the cab of the tractor..
